Pistachios are nutrient-dense nuts that offer many health benefits. They are rich in protein, healthy fats, and fiber, which help keep you full and support weight management. Packed with antioxidants, they promote heart health by reducing bad cholesterol and improving blood flow. Pistachios are a good source of vitamin B6, which supports brain function and strengthens the immune system. Their lutein and zeaxanthin content benefits eye health and protects against age-related vision issues. Regular consumption can also help maintain healthy blood sugar levels.
